8K2820021B Blower Motor for AUDI A4
Primary OE reference: 8K2820021B
Cross-reference 1: 8K2820021C
Cross-reference 2: 8EW351040261
Cross-reference 3: 8K0820021
Cross-reference 4: KM3734
Cross-reference 5: 8K2820021A
Product type: Automotive HVAC Blower Motor
Applicable vehicle: AUDI A4
Brand: AUDI
Model: A4
Electrical match: Confirm voltage, plug key and terminal count against the original motor
Motor interface: Compare flange contour, screw spacing and motor-body depth
Fan wheel check: Verify wheel diameter, height and rotation direction before ordering
HVAC function: Stable wheel rotation helps distribute air without relying on vehicle speed, making the blower important at idle and in traffic.
Installation guidance: Seat the mounting flange evenly, avoid impact to the plastic impeller, and listen for rubbing or imbalance during the first test.
Fitment basis: Check voltage, rotation direction, cable exit and the position of every locating tab against the existing blower.
Quotation information: Provide the OE number, vehicle application, quantity and delivery country
8K2820021B Automotive Blower Motor Overview
YoonShan catalogues 8K2820021B as an HVAC 8K2820021B airflow component for workshops, distributors and export buyers.
For catalogue item 6233-024, When the climate-control circuit commands 8K2820021B airflow, the electric motor rotates the 8K2820021B fan wheel inside the HVAC housing. Use 6233-024 when comparing this 8K2820021B airflow configuration.
OE Reference and Application
The primary catalogue number is 8K2820021B. The recorded application is AUDI A4. For 6233-024, Compare the OE label, plug key, terminal count, mounting flange and fan-wheel diameter with the removed AUDI unit. Record 6233-024 with the approved OE reference.
HVAC Interface and 8K2820021B installation
During work on 6233-024, If 8K2820021B airflow remains weak, inspect the filter, ducts, air doors and speed-control circuit rather than assuming the 8K2820021B motor is the only cause. Recheck 6233-024 before the lower trim is closed.
For item 6233-024, confirm that the 8K2820021B centrifugal wheel clears its housing and that the 6233-024 connector lock engages without force. After seating 6233-024, test the available fan speeds and listen for rubbing, imbalance or intermittent electrical operation linked to 6233-024.
